A method of isolating the tip of a shaped charge jet is described. The tip, thus isolated, provides a massive pellet for research in the field of hypervelocity impact. Aluminum pellets of 3.2 to 4.0 grams mass with velocities between 7.57 and 10.95mmmicro sec 25,059 and 35,478 ftsec were produced with a 3.33-in. diameter Composition B charge. For one charge design, in which sufficient observations were made, the standard deviation of the velocity was only 0.10mmmicro sec. Shaped charge scaling laws predict that pellets in the order of hundreds of grams can be ejected at equivalent velocities.
